Title: Automatic buoyancy control device
Inventor: NAGASHIMA AKIRA
IPC: B63G8/22
Filed: 1990-07-17
Abstract: PURPOSE:To facilitate the depth adjustment of a small submarine boat by controlling an air feed valve and an exhaust valve, through a control member, by the displacement of a displacement member caused by the differential pressure between external pressure and the internal pressure of a pressure chamber set to the value corresponding to the set depth. CONSTITUTION:In a small submarine boat with an air supply valve 3 and an exhaust valve 4 provided parallel on the upper part of a ballast tank 1, a steering wheel 22 is rotated/adjusted before diving so as to advance a piston 20 to set the pressure in a pressure chamber 21 to the required pressure corresponding to the set depth, and thereby displacement members 16, 17 and a control member 29 are moved to the left to open the exhaust valve 4. Submerging is performed by letting water enter from a water filling/drain hole 2 provided at the lower part of the ballast tank 1 while exhausting air in the upper space of the ballast tank 1. With the proceeding of submerging, external water pressure rises, and this water pressure is applied to the back face of the second displacement member 17 through a through hole 28. When this water pressure line is balanced with the pressure in the pressure chamber 21, the exhaust valve 4 is closed through the control member 29 to stop the proceeding of submerging.

Abstract: PURPOSE: To easily and surely executing close-up photographing by arranging a reflection mirror in a state where it faces diagonally downward, in front of the light emitting part of a flashing unit main body and a diffusion plate at the bottom end of the reflection mirror. CONSTITUTION: At the time of executing the close-up photographing, the reflection mirror 11 is located to face diagonally downward in front of the light emitting part of the flashing unit main body 13 and the diffusion plate 12 is located at the bottom end of the reflection mirror 11. Light radiated from the light emitting part is reflected by the reflection mirror 11, to irradiate the diffusion plate 12 and extinguished and diffused by the diffusion plate 12, to illuminate an object 19. Moreover, the diffusion plate 12 being a secondary light source is arranged at the bottom end of the reflection mirror 11, so that as the position of the secondary light source, the position near the optical axis of a photographic lens 30 is obtained and a secondary soft light source for making parallax extremely little is constituted.  Since the diffusion plate 12 has extinction and diffusion work, the effective guide number of a flashing device becomes small.

Title: Ferroelectric integrated circuit and manufacture thereof
Inventor: MIYASAKA YOICHI
IPC: H01L21/02
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To protect a ferroelectric oxide material, particularly a ferroelectric layer super lattice material from hydrogen deterioration, by providing a protection layer and an integrated circuit including a thin film made of a ferroelectric oxide material, and making the protection layer contain a small amount of oxygen. SOLUTION: A protection layer, in this case, a hydrogen barrier layer 130 with electrical conductivity is stacked on an upper electrode 126. The hydrogen barrier layer 130 contains titanium nitride and a small amount of oxygen is contained at the top and around the bottom. An area 131 disposed under the hydrogen barrier layer 130 extends upward from the bottom by about 10 to 20% of a thickness of the layer 130. In the same manner, an area 133 disposed on the hydrogen barrier layer 130 extends downward from the top by about 10 to 20% of a thickness of the layer 130. The small amount of oxygen is enough to decorate a grain boundary in the areas 131 and 133. TiON positioned at the grain boundary increases activation energy for hydrogen diffusion at the grain boundary. Thus, it is possible to prevent hydrogen diffusion through the layer 130.

Abstract: PURPOSE:To stop a sewing machine at a prescribed position accurately by determining the existence of working of a stop control means in accordance with the turning speed of the sewing machine at the detection of the prescribed position by a position detector and chaning the working period at the working time. CONSTITUTION:The time interval between zero crossing pulse signals generated from a waveform shaping circuit 2 on the basis of a signal from a speed genera- tor TG is counted by a register TD0 in a microcomputer 3 and the contents of the register TD0 are transferred to another register TD1. When a stop command is outputted, whether the lower position is being detected or not is checked from the turning speed of the generator TG. When a lower position detecting element 5 is detecting the lower position, the generator TG is rotated at a low specification speed for stopping until the succeeding lower position is detected without transfer to the brake ON processing for the stopping. If the element 5 is not detecting the lower position, the generator TG is rotated at the lower command speed for the stopping up to the lower position, and if the lower position is detected, the information of the turning speed at the detection time is applied to the register TD1.

IPC: F04D29/42
Filed: 1981-11-26
Abstract: PURPOSE:To enable to increase pump efficiency, by manufacturing an inner casing into a smooth form by way of one-piece molding of a synthetic resin, and thereby reducing the fluid friction acting thereto. CONSTITUTION:Although negative pressure acted to the inner peripheral surface of a suction opening 2 tends to rupture an inner casing 1 at the part thereof facing the inner periphery of the suction opening 2, a compressive force is acted to a filler material 21 that is attached to the inner casing 1 since the filler material 21 is shaped in a cylindrical form. Further, since fluid pressure acts to the  part of the inner wall surface of a pump chamber 3 located inside of the part where a liner ring 13 is inserted, the filler material 21 held in contact with the  inner casing 1 is subjected to a compressive force. Here, since the inner casing  1 is manufactured by way of one-piece molding of a synthetic resin, fluid friction can be reduced and hence the pump efficiency can be increased.

Abstract: PURPOSE:To enable execution of highly precise inspection of a number of items by separating agglutinated bodies of carrier corpuscles in accordance with the sizes thereof. CONSTITUTION:When a reaction liquid L is injected from a direction A into a gap between a base 2 and a recessed part 3a which lessens gradually from the direction A to a direction B, it penetrates in the direction B in which a vertical space is narrow, by the surface tension. Simple carrier corpuscles F1 and F2 not being agglutinated yet can move to the depth in the direction B since the diameters thereof are smaller than that of an agglutinated body. However, agglutinated bodies G1 and G2 are trapped midway according to the sizes thereof and can not move further, and the agglutinated bodies G1 and G2 are dispersed in the direction of A-B sequentially, beginning with those having larger diameters. Accordingly, trapped positions and amounts of the agglutinated bodies G1 and G2 are discriminated.
